TYPE-WRITING MACHINE.

To all fwhom. z't may concern:

Be it known that I, PHILIPPE DE CLAMECY, a citizen of the United States, of Boston, county of Suffolk, and State of Massachusetts, have invented certain new and useful Improvements in Type-Writing Machines,`of which the following is a full,

clear, and exact description. Y This invention relates more particularly to the platen carriages of front strike or other visible typewriting machines.

So far as I am'aware, typewriting machines are adapted to sup'- port paper or other-work sheets of a'length approximately the length of the platen but not sheets of paper, envelops and ,the like which are much wider than the length `of the platen carriage. To accomplish this result, it is the usual practice to provide carriages of different lengths which areforthe most part interchangeable. In such cases and particularly for machines which are of a portable character, as the Corona typewriter for example, the additional length of the carriage would be objectionable Whether as a separate attachment or as a part of the ma- `chine because the machine would thereby losemuch if not all of its compact portable character. e

object of the present inven- The primary a platencarriage which is -tion is to provide particularly adapted for typewriters of a folding character, though also adapted for other makes of typewriters, and which carriage and platen are of such a sheets of paper, long envelops, or other sheetsmay be placed about the platen so as to extend beyond the ends thereof and the carriage operated in a manner similar to the ordinary carriage.

lAnother ob]ect of the invention is `to provide a carriage in which the platen issubl stantially floatingand entirely supports'so that the w while inuse; to provide free of end ork sheet may extend a considerable distance beyond the ends of the platen and cairiage without interfering with thetravel ofthe carriage or the ma nipulation. of the work sheet.

Other objects of the invention are to vide simple and etlicient means whereby the platen may be kept in proper alineinent simple means where- `bythe work sheet may be properly guided about the plat-en; and to provide -ineans whereby the work sheet may be released to Specica'tion of Letters Patent.

on two distinct parts of the paper.

A further-'object of the invention is to provide simple and efficient means whereby the platen may be properly line-spaced.

A still further object ottheiyention is to provide a platen carriage which'iiiay'be read-l v ily made and assembled and which is effece tive in use. e

With these and other objects in view, the

invention will be hereinafter more particularly described with reference to the accompanying drawings, which form al partof this application, and will then be pointed out in the claims at the end of the description.

In the drawings, Figurel is a side elevaelevation partly brokensupport 10 may be of any suitable construction, and adapted to travel in any desired way along said bed or support is a carriage 11. This carriage has a base 12 and end sections or members 13.\ These end members 13 haveV upwardly Yextending curved and yielding arms 14 and 15, the latter being located in front of the platen` f tion of one form of platen carriage embodyf 16 and the arms 14 at the rear thereof.

Thesearms 1l and 15 act as springs and eX- ert. their force toward` the center of the platen and form substantially a cradle for The platen 16 may be of the the platen. usual or of any preferred construction and has a rubber or other impact member 17 arranged around a form or cylindrical body 18 as usual. The platen is supported lengthwise thereof between rolls 19, 20, 21, and 22. These rolls 1 9 to 22 have their ends journaled in the carriageend member, the rolls 19y and 22 beingjournaled in the arms 15 and the rolls 2O and 21 being journaled in the arms 14 of the carriage. The platen is made substantially true throughout its entire length and the rolls 19 t'o 22 also run true in their bearings and are parallel to each otherA j s riage while the rolls 21 and 22 are adapted QI-sto move bodily toward or away from the platen.l The shaft of the roll 21 at the rear of the platen is movably held in adjustable bearings or in slots 23 in the upper ends of the arms 14, and said roll is forced radially inwardlyby springs 24.v The shaft ofthe roll 22 is similarly yielding and adjust' ably held in the upper ends of the arms 15,

there being springs '25 located in slots in'said arms for that purpose. The springs 24 and 25 permit manifolding by allowing the, rolls 21 and 22 to move away from the periphery of the platen and such movement permits the platen for the same purpose 'to move away from the rolls 19 and 20. The springs curved metal plate.

as well as the yielding effect of the arms 14 and 15 maintain proper tension and frictional engagement between the rolls and the platen and said springs stake care of any slight taper of the platen and insures it working in perfect alinement.

The paper 26 will extend between the platen and the rolls 21 and 20, and forwardl between the roll 19 and the platen, and upl wardly between the roll 22 and the platen, as indicated inthe broken lines,l and takes the usual course of a work sheet in the ordinary typewriter, and by reason .of the tension of the springs 24 and 25 on the rolls 21 and 22, the work sheet will be held properly about the platen, and in such a way that the platen and all the rolls will rotate in unison. The paper is guided at the rear portion by a paper apron 27 which is in the form ofa This paper apron is supported by projections 28 on the arms 14, and extends from the roll 19 to the roll 21 and even above said roll 21 if desired. At the front of the platen are arranged paper fingers 29 which are held to bosses or parts 3 0. The bosses or parts 30 are slidable along a transversely extending graduated rod 31 andfsaid fingers and the bosses are held in an adjusted position by means of thumb screws 32 or in any desired way. The finv gers 28 and the paper apron 27 serve to guide properly the work sheetv about the platen. Above the platen and adapted to restthereon is a guide plate 33 which assists in removing and directing the work sheet from the platen as indicated by the broken-lines. The plate 33 is supported between substantially T-shaped arms34 which are looselyv mounted upon the axis or shaft 35 of the platen at the ends thereof, and at one end of the arms 34 is a roll 36 which rests against the feed roll 21 and serves to position the nasceva arms 34 and the guide plate 33. The pla-te 33 rests by gravity on the surfaceof the platen and the roll 36 is simply to reduce adapted to be flexed to a certain extent, and

this iexingmay be accomplished by means of an arm 37 the outer end of which has a finger or gripping part 38 by which said arms 15 and the roll 22 may be moved far enough to release the pressure on the platen and permit the work sheet to be adjusted about the platen or lengthwise thereof as desired.

In thestandard typewriter, the line-spacing -means is axially arranged with respect to the platen, but if the work sheet extends Abeyond the ends of the platen, the linespacing means if thus arranged would be inaccessible even if it did not interfere with the work sheet itself. To avoid this, the,

line-spacing means is mounted at the front of the platen. As shown, the roll 19 has` a gear 39 on one end of its shaft, and this gear or pinion is in mesh with a largergear 40.A

The lgear 40 is rotatably held on a stud 41v mounted in a bracket 42 projecting outwardly and forwardly from thel carriage. A ratchet wheel 43 is held to rotate with the gear 40, and adapted to engage the teeth of the ratchet wheel 43 is a pawl or dog 44. This pawl is held to an armi 45 the latter having a finger portion 46 to operate said arm. The arm is pivotally held at itsinner end on the stud 41 and is provided with a` projection, as 47, adapted to engage under a portion of the bracket 42 to position the arm substantially horizontally, but which perf mits upward movement of the arm. Asthe arm 46 is moved upwardly on its pivot the dog 44 will rotate the ratchet wheel 43, the gear 40, and the pinion 39, and such rotary movement will impart a similar rotary movement to the feed roll 19, which, owing to its frictional engagement with the ,platen or thework sheet about the platen causes the platen and vwork to move therewith a 'disytance corresponding to the extent of movej c."

ment of the arm 45; The arm 45 and pawl .L 44 may be arranged to give variablelinefy spacing as is. provided in -niany kinds of. writing machines, kthough for ordinary poses the construction shown may be one. two or three or more teethaccording vpur-,5

em?. lployed to move the handle the distance. off,A Y

` the dierent lines of print.

andere the line-spacing mechanism, the laxis of the platen may be rotated independently of the line-spacing means by knobs 48 when the work sheet is of less length than the platen itself, it being understood that any suitable construction of line-spacingmechanism may is provided whereby the work sheet may be guided and held in lproper position about l the platen; and that simple means is provided whereby the work sheet may be properly line-spaced.
